CARBURETER.

Specification of Letters Patent.

Patented Aland, 1916.

Application filed. December 14, 1914. Serial No. 877,054.

To all whom it may concern:

Be it known that 1, JOHN BRIGKEN, subject of Russia, residing atChicago, in the county of Cook. and State of Illinois, have invented acertain new and useful Improve ment in Carbureters, of which thefollowing 'is a full, clear, concise, and exact description.

My invention relates to a carbureter for internal combustion engines andits ob ect 1s to provide simple and efficient means by which aliquid-fuel is converted into vapor and mixed with air to form theenginecharge.

A further object is to provide in a carbureter automatically operatingmeans by which the desired proportion of air and gaseous fuel areautomaticallymaintained, the amount of fuel supplied being automaticallyregulated by the flow of an through the carbureting chamber.

With the above objects in view, my 1nvention provides means whereby theliqu d is fed upon a revolving plate, the liquid tending to be held;upon said plate by adhesion and being thrown therefrom by centrifugalforce.

My invention and the several features 6 thereof may be more readilyunderstood by reference to the accompanying drawings, in

which- Figure l-is a longitudinal, central sectlon of a carbureterembodying my invention;

Fig. 2 is a transverse section on the line 2-2 of Fig. 1; and Fig. 3 isan enlarged, detailed plan view of the lower end of a spacing tube whichcommunicates with the feed tube.

Like numerals of reference refer to like parts throughout the severalviews.

Referring to the drawings, the air supply chamber 1 of the carbureter issupplied with gasolene or other suitable liquid fuel from the tank orfuel supply chamber 2, said revolve by a series of vanes or blades 8,said vanes being preferably secured to and projecting from the disk 6,as shown in the drawlngs. The air suction through the chamber 1 causesthe vanes 8 to rotate,'thus lmparting a-rotary motion to the disk 6. Thespeed of rotation of said disk is thus dependent upon the current of airflowing through the chamber 1. Such fiow of air may be controlled in theusual well known manner.

I preferably provide, immediately above the disk 6 and suitably spacedtherefrom, a member 9 having at its lower end a circular, plane surfacewhich extends parallel to the upper surface of the disk 6. The opposingsurfaces of the disk 6 and the member 9 thus provide, as it were, anozzle having a contracted, circular passage, the oil tending to adhereto the two opposing surfaces. The member 9 forms'the hub portion of anannular ring 10, which ring is threaded upon the interior of the casingof the chamber 1, whereby the member 9 may be vertically adjusted toproperly space apart the disk 6 and the member 9. Threaded through themem- 6. The tube 11 projects below the end of the member 9 andserves asa spacing block for separating the disk 6 from the member 9, therebypreventing the disk 6 from rising under the action of the revolvingblade 8. At its lower end the tube 11 is provided with one or moregrooves or notches 12, through which the liquid fuel may escape into thespace between the disk 6 and the opposing surface of the member 9.Extending through the tube 11 is the stem 13 of a needle-valve of theusual construction, which valve can be adjusted to control the flow ofthe liquid from the feed 'tube 4.

The fuel tank 2 may be provided with the usual float 14: which controls,in a well known manner, the valve 15, thereby maintaining apredetermined fluid level in the tank 2. The level of the fluid in thetank 2 is preferably maintained slightly lower th an the upper surfaceof the disk 6, in order that when the engine is not running the oil willnot flow from the pipe 4: onto the surface of the disk 6. Upon. a rotarymotion being imparted to the disk 6, the centrifugal force exerted uponthe liquid in the cavity thrown out, by centrifugal force, in the formof a fine spray or vapor, which becomes thoroughly mingled with the airpassing through the carbureter l. The amount of liquid fuel dischargedinto the chamber 1 is thus dependent on centrifugal force,

which in turn is proportional to the speed of rotation of the disk 6,which in turn is proportional to the amount ofair passing through thecarbureter chamber. The proportion of fuel to air in the engine chargeis thus automatically maintained constant.

It is obvious that changes in the details of structure shown anddescribed may be made without departing from the scope of the inventionas defined in the accompanying claims.

So far as I am aware, I am the first to provide means by whichcentrifugal force is utilized for discharging liquid fuel in the form ofa spray into the carbureting chamber of an internal combustion engine.

What I claim is 1. In a carbureter, the combination ofan air chamber, arotatable member, an opposed member having adjacent parallel surfacesand means for separating said members to provide a nozzle openingoutwardly in all directions without obstruction.

2.-In a carbureter, the combination of an air chamber, a rotatableplate,having a central opening, a hollow supporting shaft therefor, afeed tube, said shaft and feed tube being concentrically mounted andmeans mounted on said shaft for rotating said plate.

3. In a carbureter, the combination with an air chamber; of afuel-discharge nozzle disposed within said chamber, said nozzlecomprising two members having adjacent parallel surfaces, said membersbeing relatively rotatable and one of them being provided with vanesadapted to be actuated by the air which passes through said chamber.

4. In a carbureter, the combination with an air chamber; of afuel-discharge nozzle disposed wholly within said chamber, said nozzlecomprising a revoluble member and an opposed stationary member; andmeans, actuated by the air passing through said fihamber, for rotatingsaid revoluble mem- 5. In a carbureter, the combination with an airchamber; of a fuel-discharge nozzle disposed within said chamber, saidnozzle comprising a revoluble member'and a member spaced therefrom toprovide a clearance;

6. In a carbureter, the combination with an air chamber; of afuel-discharge nozzle disposed within said chamber, said nozzlecomprising a revoluble plate and an opposed member; and vanes carried bysaid revoluble plate.

- 7. In a carbureter, the combination of an air chamber, a verticallydisposed fuel-supply tube located centrally of said chamber, a rotatablemember mounted about the open end of said tube, vanes carried by saidrotatable member, and a stationary member opposed to said rotatablemember, said two members constituting a fuel-discharge nozzle.
